NY/T 1969-2010飼料添加劑 產(chǎn)朊假絲酵母

本標(biāo)準(zhǔn)規(guī)定了飼料添加劑產(chǎn)朊假絲酵母的定義、要求、試驗(yàn)方法、檢驗(yàn)規(guī)則以及標(biāo)志、包裝、運(yùn)輸和貯存。本標(biāo)準(zhǔn)適用于飼料添加劑產(chǎn)朊假絲酵母。

HG 2934-2000飼料級.硫酸鋅

本標(biāo)準(zhǔn)規(guī)定了飼料級硫酸鋅的要求、試驗(yàn)方法、檢驗(yàn)規(guī)則、標(biāo)志、標(biāo)簽、包裝、運(yùn)輸和貯存。 本標(biāo)準(zhǔn)適用予以含鋅原料與硫酸反應(yīng)生成的飼料級硫酸鋅。本產(chǎn)品經(jīng)預(yù)處理后，在飼料中作為鋅的補(bǔ)充劑。

HG/T 3972-2007飼料級.碳酸氫鈉

本標(biāo)準(zhǔn)規(guī)定了飼料級碳酸氫鈉的要求、試驗(yàn)方法、檢驗(yàn)規(guī)則、標(biāo)志、標(biāo)簽、包裝、運(yùn)輸和貯存。本標(biāo)準(zhǔn)適用于碳酸氫鈉。該產(chǎn)品主要用作畜禽飼料添加劑。分子式:NaHCO<下標(biāo)3>相對分子質(zhì)量:84.01(按2005年相對原子質(zhì)量)

DIN EN 15785-2009牲畜飼料.雙歧桿菌的分離和計(jì)數(shù),德文版本EN 15785:2009

This European standard defines general rules for the enumeration of probiotic bifidobacteria in feed samples (additives, premixtures and feeding stuffs) that contain bifidobacteria as a single bacterial component or in a mixture with other microorganisms. This standard is not applicable for mineral feeds which are defined as complementary feeding stuffs composed mainly of minerals and containing at least 40% crude ash (Council Directive 79/373/EEC).

BS EN 15785-2009動物飼料.雙岐桿菌屬的分離和計(jì)數(shù)

This European Standard defines general rules for the enumeration of probiotic bifidobacteria in feed samples(additives, premixtures and feeding stuffs) that contain bifidobacteria as a single bacterial component or in amixture with other microorganisms. This standard is not applicable for mineral feeds which are defined ascomplementary feeding stuffs composed mainly of minerals and containing at least 40% crude ash (CouncilDirective 79/373/EEC) [3].There are different categories of feed samples:a) Additives containing about 10<(UP)10> colony forming units (CFU)/gb) Premixtures containing about 10<(UP)8> CFU/gc) Feeds, meal or pellets, which contain about 106 CFU/g and include complete feeding stuffs, and milkreplacers.The detection limit is as defined in EN ISO 7218.
